Abstract

Aiming at two oil leaking failures of the maintenance valve in fire prevention cabinet of transformer oil evacuation and nitrogen injection extinguishing equipment

this paper effectively analyzes the sealing gasket of maintenance valve by means of ATR-FTIR spectroscopy

thermogravimetry analysis and compatibility test with mineral insulating oil

Carries out effective test on rubber sealing gasket of maintenance valve

finds out the cause of failure and put forward suggestions.
